Push-in type fuse

Abstract

A presser spring ( 43 ) is separately formed with a fuse body ( 33 ), and therefore may be formed of a material having a high spring characteristic. The presser spring ( 43 ) is attached to a portion of peripheral wall portions ( 41 b ) to which a back plate portion ( 41 a ) is opposed, so that a mating tab terminal ( 39 ), inserted in an engagement space ( 45 ), is pressed against the back plate portion ( 41 a ) by the presser spring ( 43 ).

What is claimed is:  
     
       1. A fuse, comprising: 
       a fuse body including:  
       a fusible conductor portion having a fusing portion, and  
       a pair of female terminal portions integrally formed with end portions of the fusible conductor portion, wherein each of the female terminal portions includes:  
       a back plate portion extended from one of the end portions of the fusible conductor portion, and  
       a pair of peripheral wall portions extended respectively from opposite side edges of the back plate portion, the pair of peripheral wall portions being bent so as to oppose tip portions thereof to each other at a position opposing to the back plate portion, so that an engagement space into which a mating tab terminal is insertable is formed between the back plate portion and the pair of peripheral wall portions; and  
       a presser spring separately formed with the fuse body, the presser spring being attached to a portion of the peripheral wall portions to which the back plate portion is opposed, so that the mating tab terminal inserted in the engagement space is pressed against the back plate portion.  
     
     
       2. The fuse of  claim 1 , further comprising: 
       a housing in which the fuse body is insertable; and  
       a terminal lance formed on and by partially cutting a portion of the peripheral wall portions which opposes to the back plate portion,  
       wherein the terminal lance of the fuse body is engaged with the housing when the fuse body is inserted in the housing.
